The frustrating thing about tuberolling is that you really don't know just what you've done until at least a week or two after you've done it, unless the tubes have been freshly broken in already. It can take up to a month for a tube in regular use to take on its final sound. Fast impressions can guide you, but you do run a risk of missing something good.
A general rule of thumb is that tubes that provide a lot of gain affect the sound the most. That's usually an input tube, or driver. After all, they're magnifying the signal, which can make their effect disproportionate. An output tube is increasing current, but may not be affecting gain all that much. This dimishes the effect on the sound to a certain degree.
Ultimately, certain input tubes will sound their best with certain output tubes. An input tube that you think sounds bad with one tube in the output position may sound perfect with a different output tube. Finding the right combinations is not a job for the impatient.
